To all whomy t may concern Be it known that l, HENRY H. Tanoi's, a citizen ot the United States. residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful improvements in Excavating and Loading lvlachines7 ot which the following is a specification.

The present invention relates to certain new and useful improvements in excavating and loading machines, and has for its primary ohject to provide a machine ot this character which embodies novel features oi' construction whereby it can he operated successfully' in underground mines in 'other similar places where the limitations ot space are' such as to prohibit the usc of ordinary power shovel constructions.

Further objects of the invention are to provide an excavatinil,l and .loading machine 'which is light and compact in ,its construe tion and can he readily niovcd from place to place.l which will operate in a small amount of space, and which will excavate and loosen the material, swing it overhead and discharge it into a car or like receptacleat the rear of the machine.

The invention also contemplates a machine of tliiis character including a clipper which is constructed Without a trap door or other movable part, said dipper beingn mounted to be swung directly over-head to discharge at the rear of' the machine, one cdge'of the clipper being used for excavat- L at the opposite side thereof.

TWith those and other objects in view, the invention consists in certain novel combinations and arrangements of they-)arts as will more 'fully appear as the description proceeds, the novel features thereof being vointed out in the appended claims. For a full understanding of the inventionj reference is to be had to the following d escription and accompanying drawings, in whichz- Figure l is a side elevation of an excavating and ore loading machine constructed in accordanccwith the invention, the clipper heing shown oy tull lines at the beginning of its crowding or excavating movement an by dotted lines in both its initial movement and in its inal position which is assumed when discharging its contents into a pcciiiceton of ttcrs Patent.

Specifically describing; the present cmhodiment of the invention, the numeral i the hed ot the maciii'ie which is preieralily mov'ahly mounted no admit of tlldmachine being readily shifted from one position to another position', the said hed being shown in tl' present instance as mounted upon a tr i 2 which is adapted to travel nach and to upon the ti'acli'- 3.

fi turn table 4i is mounted upon the hed l to revolve about a. vertical anis7 the opposing faces oi' the turn table Aand hed heing;y preferably provided with annular 'ways' receiving the antifrictimi hah:l Any suitable means may ho provided tor revolving the turn 'table or this may he accomplished manually, as in the present instance.

A. pair oi" independent motors 6 and 7 are mounted upon opposite sidesf the turn table i, and these motors mayibe fr?? my suitable `and operated hyjelectricity, compres danger stcan'i,asinay einost convenient. rhe motor? corresponds somewhat in function to the crowding engine o a steam shovel and the motor 6 to the hoisting engine oi a. steam shovel.

The shaft 8 ot the motor 6 is provided with a. Yworm 9 which meshes with a Worm `gear l0 on a shaft 11, the said gearing heing housed within a suitable tfreer, case 12,

while opposite ends ot the shaft il are provided with pinions i3 Which meshl with gear wheels lll on a 'transverse shaft 15 which is arranged parallel to and under the shaft l1. Rigid with the gear Wheels 1 4' upon opposite sides of the machine are the i end thereof to the clipper 19, and having the opposite'. ends thereof curved at 132L for con- V:nectionA with crowding lcables 20.

v'.llheends ofthe cables 2O are connected to the groov'edv periphery of sheaves 21, said sheaves'being rigid with gear wheels 22 which are looselyvmounted upon opposite yends of the shaft 15 and mesh with gears 23 upon'a transverse shaft 24-which has av -lparallel and spaced relation to the shaft 15 and receives power through suitable transmission gearing/from the motor 7. A. second set of gears 25-are rigid with the shaft 24, the said gears 25 meshing with pinions 26,'upon an upper shaft 27. The middle por- 'be obvious that the motor or engine 6 is .nected by gearing to the sheaves21 so as tion of the shaft 27 is provided with a worm gear 28 which meshes with a worm 29 upon theJ shaft 30.01? the motor 7.

With the foregoing construction, it will connected by gearing to the elevating arms 16 so as to swing the same upwardly and downwardly about the shaft 15 as a pivot center, while the motor or engine 7 is con to take in 'or let out the crowding cables 20 and swing the clipper 19 upwardly or down- A j parts driven thereby. It will also be uri-- .40

wardlyabout the shaft 17 at the outer ends of the hoisting arms 16 as a pivot center. The two sets of. gearing may be proportioned to obtain any desired ratio of motion between the respective motors and the der'stood that both motors are reversible and may be operated simultaneously or successively, as mayl be found necessary.

In Fig. 1 the dipper 19 is shown by full lines inthe position B, and by dotted lines in the two dierent positions .A and C. At the beginning of the digging operation the dipper is in the position A, the elevating arms'16 being slightly raised while the dipper arms 18 are substantially vertical. By the operation of motor 6 the hoisting or elevating arms 16 are moved downwardly into a substantially horizontal position, while the motor 7 is operated at the same time to take in the cables 20, thereby drawing downwardly upon the rear ends of the dipper arms 18 and advancing the clipper 19 into The motor 6 is now reversed soas to swing the elevating or hoisting arms 16 upwardly, the /ultiniate position reached by the dipper being the'position C indicated by dotted lines, fronrwhich position it-discharges its contents into a car or other receptacle (not shown) at the rear of the machine. dipper is constructed with a solid bottom The without any trap door or other movable part and is rigidly'connected` to the dipper arms 13, so that there is no trip mechanism to be operated and there are no moving parts to get ont ot order. The edge 19:L of the dipper engages the ore, coal or'other material for loosening'the same and filling the dipper upon the crowding movement thereof, the contents of the dipper being discharged at the opposite edge 19h thereof when the dipper is swung overhead into the position C indicated hy dotted lines. The turn table 4 may be manually or otherwise operated to swing the'dipper from side to side during the excavating and llingmovement thereof, so that the dipper will operate for a. limited space uponeach side of the track 3, although the turn table may be brought back to its original position before the dipper is finallyswung upwardly and rearwardly into a discharging position, thereby insuring a proper discharge from the dipper into a car. The advantage of this coni struction resides in the fact that the dipper 19 is swung directly overhead and 'discharges into a car at the rear of the machine, thereby enablingthe device to be`successfully operated in lnarrow passages where the usual lateral swinging movement of the ordinary power shovel would be impossible. The 'expense of a trap door and trip mechanism therefor, as well as the additional labor incident to the operation of such a trip mechanism, is also avoided. y

A slight modification is shown by Fig. 6, in which the elevating arm 16b is shown as provided toward the outer end thereof with la pinion 31 which meshes with a gear segment 32 rigid with the frameof the ma- .chin,e.. A sprocket 33 which'is rigid withl the pinion 31 is connected by a sprocketk chain 311 to a second sprocket wheel 35 which isirigid with the shaft 15. This shaft v15 would be driven by the motor 6, as in the previous instance, and it will be obvious that rotation of the pinion 31 will cause thesame` to travel upon the gear segment 32 and swing the hoisting arm'lb upwardly and downwardly as in the previous instance.

A further modification is shownby Fig. 7, in which the outer end of the hoisting arm 16c is shown as provided with apinion 36 which meshes with an internally toothed gear segment 37. A second pinion38 which is carried by the hoisting arm 16 meshes at one side thereof vwith the pinion 36 and at the opposite side thereof with thepinion 39 which is rigid with the shaft 15,. .As in the previous instance the shaft 1`5 receives power from the'motor 6, and motion istransmittcd from. this shaft-through the train of gearsto the'pinion so aste rotate the latter and cause it to travel `up-and down ing arlnfl with it. .i
